EDWARD EBI, OF CEDAR RAPIDS, OWA.

CON-DU lT ELECTRIC RAILWAY.

SPECIFICATION forming part of LettersIPatent No. 541,730, dated June 25; 1895.

Application filed July 5, 1894- Serial No. 516,605- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD EBI, of Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and Improved Conduit Electric Railway, of which the following is a full, clear, and exact description.

My invention relates to improvements in that class of electric railways, in which the line wire is carried in an underground conduit, and my invention contemplates the use of an all metallic circuit, that is, a line and return wire with which a trolley makes contact, although, if desired, the return may be effected through the wheels and rails of a ca in the ordinary manner.

The object of my invention is to producea railway of this kind, having a trolley of the greatest simplicity, with its wheels arranged to run on the electric wires or conductors, and having a very convenient means of lowering or raising both wheels to throw them in and out of contact withrthe wires.

A further object of my invention is to provide a suitablemeans of supporting and per fectly insulating the wires.

To these ends my invention consists of certain features of construction and combination of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a section on linel 1, Fig. 2,the conduit and car being also shown in section. Fig. 2 is a detail longitudinal section of the conduit, and shows the trolley in connection with the conducting-wires; and Fig. 3 isa detail sectional view of the trolley and its connection with the line-wire.

The conduit may be of any usual c0n-f struction and it is arranged in the usual way between the track rails 11. Extending longitudinally through the conduit, preferably fastened to the sides of the conduit and which may be supported in any convenient way.

The conducting wires and 16 are supported 'on the stringers 12 and on these wires run the trolley wheels 17, which are journaled 0n the outer ends of the arms 18 of nonconducting material. The inner ends of the arms 18 are connected with the beveled gear wheels '19, which mesh with a horizontally rotating beveled gear wheel 20 on the lower end of the operating rod 21. supported on the brackets 22 which may be of any suitable constructionand which are supported on the lower end of the tube 23, which tube is secured to the car 24 and forms a casing for the operating rod 21, and the wires 25 and 26, which lead from the trolley wheels up through the tube 23 and are connected with the motor in the usual way. Y The current The wheels 19 are thus passes from the wire 15 through one of the wheels 17, the wire 25 to the motor, and back through the wire 26 and the other trolley wheels 17 to the wire 16, butit will be understood that if desired one of the arms 18 may be dispensed with and the return made through the rails in the usual way.

It will be seen that by turning the shaft'or rod 21 the arms 18 may be raised so as to lift the trolley wheels 17 from the wires, and this enables them to pass smoothly over any obstructions. 1

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A't'rolley for conduit electric railways,

comprising oppositely projecting and pivoted arms, trolley wheels on the outer ends of said arms, a vertical rod mounted to turn, and toothed gearing between the inner ends of the arms and the lower end of the said rod, whereby by turning the said rods the arms may be raised or lowered, substantially as described.

2. A trolley for conduit electric railways, comprising a vertical rod, agear wheel on the lower end of the rod, arms, trolley wheels on the outer ends of the arms, and gear wheels on the inner ends of the'arms, said gear wheels meshing with the gear wheel of the vertical rod, substantially as described.

8. In aconduit electric railway, the combination with the connecting wires arranged in the conduit, of a tube, bevel gear wheels carried by the lower end of the tube, arms connected with the gear wheels and projecting in opposite directions, trolley wheels on the outer ends of the arms, a vertical rod projecting up through the tube, a gear wheel on the rod and meshing with the gear wheels carried by the tube, and wires connected with the trolley wheels on the ends of the arms 10 and extending up through the said tube, substantially as described.
